Research in Motion, which makes the BlackBerry, on Friday reported a surprise loss of $84 million, or 16 cents a share, which was less than the loss of $518 million, or 99 cents a share, that it recorded in the year-earlier first quarter. Its shares fell 16%.

But despite what the smartphone maker has had to endure in terms of competition in the not-insignificant form of the iPhone and Google 's Android devices, its war chest keeps getting bigger.

Today’s results – including that increasing cash pile, pose some interesting questions. Like what it plans to do to market its devices. Or why it didn’t reveal how many of its new BlackBerry 10 devices it shipped, leaving some investors and company watchers scratching their heads.
